A nationwide survey conducted by researchers at the University of Michigan concludes that U.S college students are more likely to use marijuana than cigarettes on a daily basis.

The study, noted in a story on wsj.com, also said the use of e-cigarettes and water pipes, or hookahs, is on the rise, but these devices are relatively new and usage was not fully tracked.

Illicit drug use was reported by almost 40% of students, which is up from 34% recorded in 2006, but down slightly from the 2013 number of 41%.

The researchers attribute the increase to marijuana, but also said use of amphetamines and ecstasy were on the rise as well.  Cocaine use among students is not as popular, but did see an increase.

Almost 6% of college students in the survey say they smoke marijuana on a daily, or near-daily basis, as compared to 3.5% surveyed in 2007.  Students also are less likely to believe pot smoking is dangerous, with 35% of high school students saying they believe it is harmful, down from 55% in 2006.

Cigarette smoking is decreasing among college students.  The survey posted that around 5% smoke cigarettes daily, down from 19% reported in 1999.

More students are looking for alternatives to cigarette smoking.  The use of flavored e-cigarettes and hookahs almost doubled from 2013-2014, according to results from the 2014 National Youth Tobacco Survey.  Some 13% of students say they use e-cigarettes at least once per month.

About 5% of students reported having been a participant in binge drinking, a number that is on the decline.  Binge drinking is defined as having five or more drinks in a row.  That number, though, is still higher than their peers who are not attending college.

The University of Michigan has been conducting the study, known as Monitoring the Future, for 35 years, with partial funding from the National Institutes of Health.  The survey is conducted on more than 1,000 full-time college students across the country.
